That siding is already showing signs of delamination along the bottom (edge takes on a rough appearance + curving outward). T1-11 can hold up fine, as long as it is primed & painted very thoroughly from new. Most critical is along the literal bottom edge (that faces the ground). This is where it takes up moisture and begins the delam process. If this edge is primed & painted very well, that won't happen as long as you keep on top of it every few years or so. But once it begins, you can only postpone the inevitable, or cut it off. I also caulk all nails prior to priming, which is a huge pain but helps seal out moisture. On a previous house, I had sawed 2ft. horizontally off the bottom & replaced with marine-grade plywood, then vapor barrier & Hardieplank lap siding over all. Double-thickness = better R value, quieter too. BUT, this only works if there is sufficient reveal on window casements to allow the extra thickness.

I have had T-111 siding on my stand alone shop 60'x26' for 53 years now have never had a problem I paint the south side of shop every 6 years and the lee side every 8 years ... still looks great ! I use a roller and I do the grooves with a brush , takes time but well worth it

As far as prep, how do you recommend washing it before scraping/ re-painting? Bleach? Power washer? Detergent and brush?

Do u have any tips when painting over nails to have a clean and seamless look ?

Thanks. If left unpainted or just stained, does it easily take in water n warp, esp toward bottom? Does it need to be sealed w something before/after stain? Thank u,

Can you recommend a good airless sprayer for DIY amateurs? I am painting a 24x24 garage and am weary already just thinking about paintbrushes and rollers!

Um. What about the grooves again?

My ceiling is like that and i wanna paint it and leave it white, so i needed to see how best to do it 🤔

What kind of an airless sprayer were you using?

We have T1-11 siding which has been stained very dark brown. Do they make a primer for stain ? I would like to change our house color to dark blue stain. Is this possible?

thx for making this video. I am considering using timber oil on my t1-11, have you used that product before on this siding? what I have is all wood I believe but it has treated knot holes if you know what I mean, as well as elliptical cutouts which I presume are where larger knots were removed and then replaced with an elliptical shaped piece of wood. not sure how this will look with the timber oil. any idea? thx :)

How well does this type of siding hold up?

Title says how to paint, yet you dont offer any tips of what type of primer or paint. Useless video.
